Seems like Apple wants a piece of the imaging business. The Cupertino, Calif., firm recently filed a patent for a unique flash (not Adobe's Flash, which won't work with iOS) for cameras that is said to optimize the lighting on the subject.

The patent shows an array of flash lights that point at different directions, so we presume the camera will detect where the subject is and turn on the nearest flash.

Gadget blog Gizmodo said such an implementation could make its way to iOS devices such as the iPhone and iPad, and even to video cameras.
